ProbeGuard

Clean Sensors, Clean Data

ProbeGuard controls biofouling on various moored sensors by enclosing them in a chamber that is opened and flushed to collect data. A dilute chlorine solution is periodically added to the chamber to bathe all sensors in the anti-foulant. Results from multiple environments have been impressive.

ProbeGuard saves all instrument data to nonvolatile memory that can be easily accessed over the communications port by an on-site user or remotely via an automated data collection system (telemetry) such as Green Eyes W2W.
